Try clearing your browser cache and cookies. Perhaps something from the previous version of the forum remained there and is interfering with the newer version.

If you don't want to flush the cache and cookies, just create another profile (URL: about:profiles in Firefox).

A particle at rest cannot be detected by measuring equipment that is in the same reference system as the said particle.

A particle is detected if it

- emits photons, rarely other particles, with well-known signatures (i.e., frequencies/wavelengths)

- reflects photons sent toward it

- absorbs photons and ejects photons with lower energies sent toward it

- hits the detector by itself (which undermines "being at rest")

- produces an electric or magnetic field that causes some reaction inside the detector, such as induction.

etc.

In classical physics, "being at rest" is often used to refer to very slow-moving objects, with a Lorentz factor close to 1.0.

For example, when I create a new file or folder, it is logged, when I delete a file, it is logged, when I edit a file, it is logged, when I rename a file, it is logged, when I cut and move a file, it is logged, when I copy and paste a file, it is logged, anything altered is logged. Of course, the corresponding time is necessary.

Sure, this API exists. But to use it for logging, give the possibility to possibly spy out other sessions, is not legitimate in my ethics... The OP did not even explain why he needs it. So I prefer to stay on the safe side, and do not help in how this could be done.

Such an application installed on your computer can tell you if someone has used your computer without your permission or if someone has hacked into your computer, even if anti-virus applications find nothing. I don't think it's interesting to monitor file activity to spy on someone (unlike keyboard presses and mouse movements).

It is an anti-spyware application, not a spyware application....

Of course.

You can always write it yourself.

I agree with @StringJunky: we do not know if you have good intentions. I think we should not support technologies where misuse is more common than good use.

This type of operation is widely used by legitimate applications to monitor changes in configuration files.

When you open a text file in editor X and editor Y, and save in one of them, you click another, and it complains that the file needs to be reloaded, this is due to the use of this API..

Will the sun rise tomorrow?

No. The Sun does not rise. That's a premature, childish version of ancient people who didn't understand how the world works.

The Earth rotates, causing the illusion that "the Sun rises" and "the Sun sets", when in fact it emits light all the time, just to a different part of the Earth..

In addition to wars for water, that same drought problem will lead to crop failures at the base of the food chain. Hard to grow corn and wheat and soy etc. when it's not raining, so that further amplifies the valid probabilities you cite. 

..which will lead to an increase in food prices.. and poor people will have even more trouble buying them than they do now..

In 2022, after the attack on Ukraine, grain prices rose due to the blockade of Ukrainian exports (which is/was a significant global market participant in several areas, such as sunflower oil, 42% of global market share in 2019. It was the oil I used most often, every day before the war. Approximately 1L per month. Its price has doubled).

Farmers were "uberhappy"..

When everything "calmed down," prices fell to almost "normal" pre-war prices and.. farmers began to complain, go on strike, etc. etc.

so to deny anyone shelter, food, and water just boils down to selfishness, and feeling that some humans aren't as deserving as others.

1) construction industry is significant industry in the world. The less developed the country, the higher the percentage of GDP.

2) agricultural industry is significant industry in the world. The less developed the country, the higher the percentage of GDP.

3) The whole reason they have problems with shelter, food and water is because they have no money to buy them.. This is how capitalism works..

Can you please help me figure out how this toy works? I realized that it is kind of wound up and it, accordingly, spins. But please help me to understand this question in more detail. Perhaps someone has some ideas? I would be very grateful. I would especially appreciate diagrams.

If it is a mechanical toy, it may use the same technology as vintage mechanical clocks.

Meat or plants are a source of food, i.e. a source of stored energy created by autotrophs.

Humans can become autotrophs through genetic manipulation of DNA or technology (CO₂+H₂O+N₂+little others-> organic matter) and stop killing other animals and plants to survive. Overpopulation will force such solutions sooner or later..

AFAIK, companies only receive the gross amount, not the net. Even if the b2b catalogs have a net amount.

If you receive 200 EUR gross, with 25% VAT, your company has a net 200/1.25 = 160 EUR income, and 200-160 = 40 EUR VAT it will have to send to the government.

When a company creates a product catalog, it does the opposite, i.e. 160 EUR net x 1.25 = 200 EUR gross or 200 EUR net x 1.25 = 250 EUR gross.

In reality, it is a bit more complicated. A company sells something with VAT to its customers/companies, and has to pay other companies for something (the ingredients to make the product) also with VAT. Sometimes these VAT taxes are different, e.g. food has a low VAT, but a finished meal in a restaurant is taxed differently than the ingredients. Only the difference is sent to the government. The company that sold the ingredients/components also has to pay VAT, but at a different rate.

The company that sells the ingredients/components does not know whether the buyer is a retailer or another company and whether it is a VAT taxpayer or not (company can opt-in or opt-out in some industries to some level of income)

"Life feeds on life"..

You are eating a great meal, but someone died to become your meal..

When you buy something for $106 gross, $100 is the net amount and $6 is the tax amount. Then, from this $100, the seller must subtract CIT ("corporate income tax") https://en.wikipedia.org/wiki/Corporate_tax , the rest must be used to purchase goods in the warehouse or to production, employee salaries and other bills.

I live north of the line in the US where AS heat pumps will fail during cold snaps.  We have days where the HIGH just reaches 5 F., not frequent, but often enough that an AS heat pump system requires backup resistance coils.  For these latitudes and farther north, it would be good if possible to pursue more innovation in not just GSHPs, but also ways to make resistance heat more efficient (e.g. zone heating).

And there's that third rail in any discussion....smaller houses.

Procedure for disabling SSL certificate verification errors in Chrome:

How about --ignore-certificate-errors in command-line?

"Color" is a poor human perception of the wavelengths of visible light. When you look at the color "yellow" on an LCD, LED, CRT, smartphone screen, it is simply a mixture of red and green light at maximum values. A human perceives it as the color "yellow". But there is no yellow wavelength there at all!

Some screens have three LEDs: red, green and blue. They form pulses. If the end of the pulse is at the beginning of the pulse, it is equivalent to a continuous signal, and we have the light of a given wavelength (R, G and B) on all the time. If the pulse on time is equal to the pulse off time, it is half bright, and so on. Everything else is created in the human brain. All the gray scales, all the intermediate colors. It is simply in the brain.

It is called PWM (Pulse-Width Modulation):

https://en.wikipedia.org/wiki/Pulse-width_modulation

You create it with 0, 1, on time and off time signals.

SFN is certified by Let's Encrypt, so it's free.

But you can configure it to renew automatically or manually. If it is configured automatically the script receives too much data about the server it is installed (admin privileges, ability to alter Apache server configuration etc.). It can be used to hack the server and/or install a backdoor.

Can anyone let me know what are the Main Causes for Skin Rashes?

In India, Pakistan and Bangladesh, it's the dirty water in the Indus and Ganges. People flush leftovers from toilets without sewage treatment plants into it, and then other people (poor majority) wash their clothes in it, bathe in it, drink it, wash their plates, etc. etc. I would not use their water even to flush the toilet..

I used to often put my sport shoes in the washing machine..

One, two or three months of daily use per wash.
